Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to overcome the low bonding strength, complex composition of glue and high production cost of easy-pull removable adhesive tapes in the prior art. The risk of low stress will lead to easy delamination between the base material and the tape during stretch removal, and defects such as partial breakage that cannot be completely removed

Abstract

The invention discloses easy-to-pull removable adhesive tape with a thermoplastic elastomer base material which is a styrene segmented copolymer thermoplastic elastomer base material. The adhesive tape is prepared from the components in parts by mass: 80-150 parts of styrene segmented copolymer thermoplastic elastomers, 75-130 parts of tackifying resin, 100-350 parts of methylbenzene, and 5-15 parts of color paste. The adhesive tape with the thermoplastic elastomer base material is double-faced fixing adhesive tape with high bonding strength, can be used by being pasted after release paper ora release film is peeled off and can be removed by being pulled as needed, so that repairing and maintenance of electronic elements are convenient and rapid.

Description

Technical field [0001] The invention belongs to the field of adhesive fixing tapes, and in particular relates to a thermoplastic elastomer substrate easy-pull removable adhesive fixing tape. Background technique [0002] Tape products, as essential daily necessities in modern society, play an important role in electronic products, handicrafts, metal, glass, toys and other fields. Different types of tape products play different roles in different industries. As we all know, tape products are becoming more and more popular in modern electronic products such as smart phones and tablet computers. However, in the use of many tape products, they are only used for temporary fixation during the process of heavy industry and product processing. At the same time, staff are handling products. When after-sales maintenance or recycling needs to be disassembled, many electronic components are difficult to disassemble after being fixed by tape, which greatly reduces the use efficiency of the p...
